Theorem caovdi

Description: Convert an operation distributive law to class notation. (Contributed by NM, 25-Aug-1995) (Revised by Mario Carneiro, 28-Jun-2013)

Ref Expression
Hypotheses caovdi.1 ⊢ A ∈ V
caovdi.2 ⊢ B ∈ V
caovdi.3 ⊢ C ∈ V
caovdi.4 ⊢ x G y F z = x G y F x G z
Assertion caovdi ⊢ A G B F C = A G B F A G C

Proof

Step Hyp Ref Expression
1 caovdi.1 ⊢ A ∈ V
2 caovdi.2 ⊢ B ∈ V
3 caovdi.3 ⊢ C ∈ V
4 caovdi.4 ⊢ x G y F z = x G y F x G z
